AUTOMOBILE-TIRE.

' of which the following is a specification.

I am aware ofV This invention relates to anti-slipping or anti-skidding devices generally.

The invention :is used in connection with vehicle tires, athletic shoes, and the like in which metallic surfaces are combined with elasticv or :other non-metallic surfaces, such as the tread of a tire structure whereby to increase or augment the traction action of the tire against the surface of the roadway,

the existence of metallic-.surfaces whichv are separable Jfrom the tire? and also metallic and composition bodiesjf'which are constructed as a partl ot the tire land designed for the purpose above mentioned. In that class 'of tires in which the metallic or composition bodiesare made asa part of the tire,iobjection has been taken to the manner of -securin the same to the materials of the tire, certaminadequateness infthe associa tion of the parts resulting in a material in# jury.V such as disintegration to'the ibers of the-'tire structure. molded directly in the elastic surface or tread of the tire have creep around the tire, resulting in bruising the tire along radial lines andrendering the same delicate to' the action ofthe air pres? sure within the shoe. 4

In that classof anti-skidding devices which are separable or detachable from the tire, laborious operations are necessary in effecting their final application at the time of emergency and in practice it has been found only detracting from the apthe wheel, they become contribthe transmission of harsh and object'onable noises with incidental injury to that while not pearance of" utary to the mud shield of the vehicle incident to centrifugal action as the wheel revolves.

' In the invention about to be specifically:-

described, I provide an anti-skiddin or antislipping device which will lend to t e graceful design and beauty of the tire, one which will render the Specification of Letters Patent.`

These devices which are.

a strong tendencyI to fr; being -`however,

tions are necessarlly made to the precise structural details therein exhibited, but that Patented Mar. 26, i918.

Application led October 17, 1916. Serial No. 126,175. Y

ing any season of the year; one in which traction efficiency is set up face of the tire; one which will be simple, strong and `durable and peculiarly associated with the different ing the tire where y it is held from accidental dislocation or circumferential creeping.

As a principal object in view I provide` a plurality of radial studs of relatively hard or non-yielding material whose qualities are equal to the qualities of rubberor any like composition of matter to resist wear and friction whereby the studs which are projected into recesses of the elastic material of the tire, will always come flush with the tread of the tire to enable the studs and the tread to be simultaneously subjected to the same wear and impingement against the roadway. I prefer to mount these studs in recesses so thatthe outer r endslof the studs the formation of a substantial relatively rigid inetalliegtraction sur rounding walls of the mentioned recesses. v With he above and other objects in view wli'cnwill appear as the nature of the invention is better understood, the same consists the be fu1ly"described-,and particularly point 'ediiout 1n the claims. y

.In the accompanying drawing, have been illustrated certainforms of the invention, it

understood that no limitachanges, alterations and 'modifications within the'` scope oi?` the claims may be resorted to Figure il is anedge view of a conventional form oftire illustratingthe application of the invention thereto.

'l same sultable for use durfl Fig. 4c is a perspective view of the device on the tread sur? lies of material constitutimproved construction and novel- `l arrangement of parts which will hereinafter showing the several' constituents thereof separated for the purpose of clear illustration.

Fig. 5 is a bottom plan view of a shoe constructed in accordance with the invention.

Fig. 6 is a section through a portion of the shoe.

In carrying the invention into practice and on reference to Figs. l to 4 inclusive, I provide a tire l, of substantially standard formation, except for the peculiar manner of `forming recesses 2, in the elastic material of said tire. I do not wish to limit myself to the manner of selecting an arrangement of recesses and the illustration furnished in Fig. 1, is to be considered merely conventiona In this arrangement, I provide two annular sets of recesses 2, which are disposed on opposite sides of the central line of the tire with the recesses of one set extending at an opposite angle to the recesses of the next adJacent set. 4

Each recess extends into the tread of the elastic material 4f, of the tire and it opens at its inner end onto the textile material 5,

y of said tire. In the recess at the base thereof In this manner, wiched between sald strips for a purpose to a strong connection terial 4, of the is a str1 of thin material 6, preferably metal. 'lPhis strip comes in contact with the fabric 5, exteriorly of the tire structure, while arranged interiorly of said structure and against the fabric, is a second strip of thin material 7 preferably metal.

the fabric becomes sandbe hereinafter described. Y

Studs or pins 8--8, extend through each recess and to a point Hush with the tread surface of the elastic material of the tire. hey are provided with stems 9, which extend through the fabric and through both plates` 6 and 7, and are upset at 10 against the innermost plate. This method provides tire whereby they cannot casually separate from the tire under trying strains.

The ins or studs are formed of some hard su stance, preferably metal, which will have the same quality of resisting wear and friction as that possessed by. the rubber matire. The studs are spaced relatively from each other and also from the walls of the recess in vwhich they are mounted. They extend through the full depth of the recess in order that their effective traction surfaces will come flush with the tread surface of the tire. In this manner, the studs are exposed at the tread of the tire in order that they will take 'firm and effective purchase against slippery and muddy roadways and positively prevent the machine from slipping or skidding. Through the fact that the said studs have wearing qualities which are approximately the same of the studs with the recarsi as the qualities possessed by the rubber tread of the tire, they will be uniformly worn down as the tread is evorn so as to be always effective for their intended purose and never forced to protrude to points eyond the recesses of the tire where they would mar the road-bed. It is also found that by ymounting 'the studs in a recess in the tire, the angularity of the walls of the tire against the roadway and considerable strain, both torsional and lateral, is relieved from the studs.

In order that the inner tube of the tire will be protected against injury through contact with the studs, an inner lining of suitable tough material 11, is made up as a part of the tire and arranged. to cover the inner ends of the studs as clearly shown.

The invention is by no means limited to use in connection with tires as is evident upon reference to Figs. 6 and 7,'wherein an athletic shoe 12, is shown. The sole or wear surface of the shoe is provided with recesses 13,v in which studs 111 are disposed. One stud is preferably provided for each recess and it is assoclated with plates 15 and 16, which are similar to' the plates 6 and 7, elsewhere set forth. The reduced ends or stems 17, of these studs are passed through the sole and `upset at 19 against the innermost plate. y The heel of the shoe is correspondingly constructed. A shoe designed in this manner is admirably adapted for use in playing such games as golf, tennis, basebalh and the like in that a lirm footing of the player against 4the surface of the ground can be obtained which enables him to satisfactorily carry into practical edect many different movements of the body without danger of slipping.'A

What is claimed as new is 1. A non-skidding device for tires comprising a tread surface of rubber having a recess extending through it, a layer of fabric underlying the rubber, a metal plate within the recess and lying upon the fabric, a'second metal plate beneath the fabric, and a metal stud whose body is mounted in said recess remote from its walls and whose inner lportion has a reduced stem` passing through oth plates and the interposed fabric and upset on the inside of the innerV plate.

2. In a non-skidding device, superposed layers of material, the outermost having a recess extending therethrough, a metal plate fitting snugly within said recess upon the outer' face of the underlying layer, a second metal plate engaging the inner face of the innermost layer, a metal stud within and spaced from the walls of said recess and having its outer end flush with the outer surface of the outermost layer and having recess serves to increase the traction of the 1 through,

'10 layer.l a second a reduced stem extending through said layers and said plates, and means on said stern engaging the second named metal plate for holding said stud against displacement.

3. A non skidding device comprising superposecl layers of material, the outer layer having a recess extending entirely therea metal plate itting snugly within the outer face of the inner metal plate upon the inner said recess upon face of the inner layer and a. metal stud within and spaced equally from the Walls and having through said l a reduced stem extending ayers and both of said plates and having its inner end upset upon said second plate.

In testimony whereof I aix my signature.
